)T he invention aims to providea 'new and improved form of knock-'downstove of sectional construction, this construction being' suchthat anupper, oven-and-iiue-containing wall and aj top .secured thereto, imaybe disposed within i aglower, fire-retaining.

wall when thev stove is disassembled.

1With the foregoingin view ,the invention resides in the novel'subjectinatter lierein fatter describedand claimed, the descriptionbeing supplemented by the Vaccompanying drawing.

Fig. y1 is a front elevation of the stoveset up for use.v v

Fig, 2, is a vert-ical sectional View on line Qa of Fig. i.

Figs. 3 and 4 are horizontal Ysections on the correspondingly numberedlines of Fig. 5 is a vertical transverse section on line 5-5 of Fig. 2.

Fig. 6 is a vertical sectional view lshowing the sections of the stovedisassembled.

Fig. 7 is a vertical section illustrating the I manner in which thesections of the stove are engaged with each other when they are to becarried from one place to another.

' The form of construction selected for illustration in the presentapplication, will be rather specifically described, with theunderstanding however, that within the scope of the invention asclaimed, variations may be made. e

In the drawings above briefly described, the numeral 8 designates abottom which supports the fire when the stove is in use, said bottompreferably having detachable legs 9. At its periphery, this bottom isprovided with an upwardly projecting continuous flange 10, which is.spaced inwardly to some extent from its peripheral edge. Resting uponthis peripheral edge portion of' the bottom 8 and 'fitting removablyaround the flange 10, is a lower wall 11 which retains the fire when thedevice is in use, said wall being provided with a fuel-feeding anddraught-controlling door 12 which is hingedly .supported at 13 and heldclosed by a suitable spring catch or the like 14.- The upper end of thiswall 11 is contracted as indicated at 15, and a downwardly facing,beveled, internal shoulder 15@L is formed at the lower portion of thereduced end, while a similar but upwardly :facing shoulder 15b is alsoprovided, externally.

iRjeiiiovably fitting faroiu'nd l the contracted upp'erend 1 5 of thelower 'wall 11, and resti ing'onslioiil'der15b, is an upper, continuous,oven-andlflueLcontaimng wall 16, this upper wall beiiigof less 'heightand oless diameter than fthe wall'i11so that it may be received Awithinthe latter 'when the parts are tobe nested-for y carriage from one placeto another or for`s`t orage, as willbe clearffrom F ig. 7 The"oven 1 7land the smoke flue 18 within the confines foftheiwall 16, are prac-Ytically identical with theloven "andfflue of our S. Patent`No.-1',464,271 andhence 'need notbe 'described in detail. vItn'ia'y bementioned however, r4that the hinged oven door 19 is h eldnormallyclosed by spring catch 20 (Fig, '41) s'provided vwith an external handle21, byem'eans 'of which `it maybe "opened, and is formed witha recess 22into prefer to provide the linterior of the oven with opposed aperturedlugs 23 with which the downturned ends 24 of rods 25 may be engaged,providing a grating upon-which to rest baking pans or the like.

A top 26 is secured upon the upperr end of the wall 16 and is preferablyprovided with a vdownwardly projecting continuous flange 27 whichsurrounds said wall, said top 26 being also provided with a smoke outlet28.

When the stove is to be carried from one place to another, the sections8, 11 and 16 are disconnected as in Fig. 6, and the legs 9 are removed.Then, the legs are placed in the oven 17, the section 16 is insertedinto the section 11 and the bottom section 8 is again applied tothesection 11. vThus, a' compact nested structure is produced which mayreadily be carried in small space, for instance in an automobile.Attention is invited to the fact that when the parts `are nested, asseen in Fig. 7, the top 26 abu-ts the shoulder 15a holding the section16 against loosely rattling in the section 1. The legs 9 and rods 25 maybe wrapped to prevent rattling if desired.

When the stove has reached the point at which it is to be used, it maybe quickly and easily assembled, and used to advantage.

It will be observed from the foregoing that a simple, inexpensive anddesirable con-V or condensed for earryinv or storage, as oecasion maydemand. lence, the stove is well adapted for camping purposes, but isnot restricted to this particularl field of use.

7e claim: Y

l. A knool-down'stove comprising a tiresupporting bottom, alire-retaining wall removably Connected with said bottom, anoven-and-iue-containing wall removably connected with the upper end ofsaid fire retaining wall, said oven-and-flue-oontaining wall being ofless diameter than said fireretaining wall and being receivable wit-hinthe latter when the stove is disassembled,

and a top secured to the upper end of the oven-and-flue-containing walland also receivable within said fire-retaining wall; the aforesaidbottom being re-applioable to the lower end of the fire-retaining wallafter in- .sertion of the other wall and the top therein.

2. A structure as specified in claim l; the upper end of saidlire-retaining wall being reduced, providing an internal downwardlyfacing shoulder and an external upwardly facing shoulder, the externalshoulder limiting downward sliding of the ovenand-flne retaining wallwhen the stove is set up for use, the internal shoulder abutting saidtop and holding the same and said oven-and-iueretaining wall againstupward movement when these parts are within the fire-retaining wall.

8. A knock-down stove comprising a firesupporting bottom having anupstanding annular flange; a continuous tire-retaining wall removablytelescoped with said flange, said wall being Contracted at its upper endprovidinga downwardly facing internal shoulder; anoven-and-flue-oontaining oontinuous wall having its lower end removablyteleseoped with said contracted upper end of the fire-retaining wall,said oven-andflue containing wall being of less height than thelire-retaining wall, and a top having a smoke outlet and a continuousdownwardly projecting flange, the latter being telescoped withv andsecured to the upper end of said oven-and-flue-eontaining wall; theoven-andflue-eontaining wall and top being receivable within thelire-retaining wall when the steve is disassembled, said top thenabutting said shoulder, said bottoml being ie-engageable with the lowerendrof said tire-retaining wall to hold the nested parts in nestedrelxition with each other.
